It all smells like normal drive by wire DSG operation to me. Do a few searches on DSG hesitation and you'll find a few threads with people alarmed after getting into a new DSG car.
At T junctions I got used to accelerating early if I wanted it to behave like a normal car.
You get used to it, but it catches you out when you switch to a 'normal' car as you start moving much earlier and will t-bone someone if you don't adapt.
For some reason most of us just accept it, but others have installed a product called a sprint booster to eliminate this and say the car is more responsive off the mark.
I saved the money and just learned to plant it, and plant it early! Supposedly the DSG learns how you drive and adapts the shifting to suit. I never noticed that so it either does a great job or doesn't do it all.
(my experience is also in a blue my09 Pirelli in Perth, not that it really matters )
